<![CDATA[Quality improvement is basically how to overcome various problems that will arise to achieve the expected quality. Quality improvement is an activity to measure performance, benchmarking with standards and any systematic effort to improve performance in order to achieve expected standards. In improving the quality of this caricature image using a maximum filter and a median filter is basically a method to reduce or eliminate noise in a digital image or image, smoothing with a median filter to replace pixels with the highest value of a series formed from a matrix that matches the size of filter window. This filter works by selecting the intensity of the pixel in the middle, after pixel_pixel included in the filter is sorted]]>

<![CDATA[In this era of globalization, it is very necessary to have an information system that is fast and ready to use due to increasingly sophisticated human civilization and humans themselves are required to be able to adapt to these developments. Especially in the development of sports in information technology. The application design process carried out is still difficult to find the meaning of certain sports terms in sports. In order to overcome this problem, the author applies the apostolico-giancarlo algorithm to the application of mobile-based sports terms that can facilitate the information search process, compared to those who still have to search for books which require a relatively long time in searching for the meaning of sport. With the program design that has been made by the author for the general public, especially sportsmen, it is hoped that it can help in the process of finding information. The program in the form of Eclipse Juno consists of several searching, biodata, and closing]]>

<![CDATA[Data security and confidentiality is one of the most important aspects in today's information systems. Due to the rapid development of science and technology that allows the emergence of new techniques, which are misused by certain parties that threaten the security of the information system. The fall of information into the hands of other parties can cause harm to the owner of the information. Therefore we need a way that can provide security for the data, one of which is using cryptographic techniques. Cryptography technique is a science or art in fulfilling security aspects in communicating by changing the content of information into incomprehensible information. One of the algorithms that can be used is the Loki97 algorithm, which is a cryptographic algorithm that uses the Feistel network system. The process carried out in this study is to first encrypt the text file using the Loki97 algorithm, then the results of the encrypted file will be compressed using the Adaptive Huffman Code algorithm, resulting in an encrypted and compressed file.]]>

<![CDATA[In the era of technology in the field of multimedia, especially in processing moving images or often called digital video, it is very fast and competes in image and sound quality. Video files in MP4 format are very widely used today on social media which results in little storage space remaining in memory. Data compression is a process that can convert an input data stream (original data) into another data stream (compressed data) which has a smaller size. The compression process is the process of reducing the size of a data to produce a digital representation that is dense or compact but can still represent the quantity of information contained. Digital video is a computer file that is used to store a collection of digital files such as video, audio, metadata, information, chapter divisions, and titles at once, which can be played or used through certain software on a computer. There are many data compression methods currently available, but in this study the working principle of the EZW method will be discussed. The Embedded Zerotree Wavelet (EZW) method is an image compression algorithm that is simple, very effective, has properties where the bits in the bit stream are sorted according to their importance and produces a fully embedded code]]>

<![CDATA[Digital image is an image that can be processed by a computer. Digital images that are not allowed to be known by others or are said to be private and are not allowed to be manipulated by other irresponsible parties. The act of manipulating, hijacking or tapping the image will cause harm to the owner of the image. The technique to reduce these actions is to use cryptographic techniques. Cryptographic techniques are very well known for securing information with a password that only the owner of the image understands. To strengthen the results of the encryption carried out by the Vigenere Cipher Algorithm, modifications are made to the Random Number Generator. The Random Number Generator used is Linear Congruent Generator which has linear recursive properties combined with modulus. So the combination of vigenere cipher with random number generator Linear Congruent Generator is very difficult for other parties to abuse the image]]>

<![CDATA[Text files have a large size that affects the storage space and the sending process. This size is a factor in how much storage space will be used and how long it will take to send files. The longer the text, the larger the size. Large sizes can be overcome by doing the compression process. Compression is done to reduce the size of a file. Compression algorithms that can be used are sequitur algorithm and elias gamma code algorithm. The advantage of the sequitur algorithm is to replace 2 characters side by side with 1 terminal character in the character set, while the advantage of the elias gamma code algorithm is to replace the initial bit of the character with a gamma elias code bit. The two algorithms will be combined to produce a smaller size than the previous one]]>

<![CDATA[Currently we are in the era of the digital world, there are lots of equipment that have tools to record photos in the form of cameras found on smartphones. The weakness of smartphones is the small storage space, so users must be good at managing files stored on the smartphone. There are so many applications in smartphones that provide facilities for sharing images. This of course will greatly burden the storage space of the smartphone because it stores image files which are generally large in size, especially if the image files are the same or duplicate, of course it is very burdensome for storage space. It will be very difficult to distinguish an image file without looking at the contents of the image file. So if you want to distinguish one image file from another, the user must see the contents of the image file and this will certainly be very difficult. For that we need a method that can be used to identify the same image file or duplicate image files so that a decision can be made to delete the duplicate document files so as to save storage space. In cryptography there is a hash function which is a one-way function that can generate the identity of a file, where if the image file contains the same content, it will produce the same hash value. It can be used to identify the same or duplicate image files. In the hash function there is the MD5 method or Message Digest 5 which is one of the hashing algorithms that is often used to encrypt data with a length of 128 bits. By applying this algorithm to the file scanner application, the results of the image file search are grouped based on the same hash value and users can make it easier and faster for users to delete duplicate image files without having to open and view the contents of the file]]>
